[0002] Polyacrylamide is a linear high molecular polymer. The product is mainly divided into two forms: dry powder and colloid. The main chain of polyacrylamide carries a large number of amide groups and has high chemical activity. It is an extremely important oilfield chemical. The production of polyacrylamide drag reducer uses acrylamide aqueous solution as raw material. During the production process, it undergoes polymerization reaction under the action of an initiator. After the reaction is completed, the polyacrylamide gel blocks generated are granulated, dried, and crushed to finally obtain polyacrylamide products.

At the same time, during the reciprocating movement of the straight plate, the opening on the straight plate continuously overlaps with the discharge opening of the feed funnel, so that the material discharged into the crushing box can be reciprocated and intermittently controlled to avoid a large amount of polyacrylamide entering and affecting the crushing efficiency of the crushing box.
